Quick Image Viewer (qiv) is a very small and fast GDK/Imlib image viewer designed to replace the classic image viewers like xv or xloadimage. It features setting an image as an X11 background with a user-definable background color, fullscreen viewing, a screensaver mode, brightness/contrast/gamma correction, real transparency, zoom, slideshow, support for external programs, and more. It runs on Linux (libc5/glibc), Solaris (SunOS), FreeBSD, and HP-UX.
